The HQ-9 (Chinese: 红旗; pinyin: hóng qí, "red flag" or "red banner") is China’s new generation medium- to long-range, active radar homing air defence missile.
The naval HQ-9 appears to be identical to the land-based variant. Its naval type HHQ-9 is equipped in the PLAN Type 052C Lanzhou class destroyer in VLS launch tubes.
The land-based HQ-9 system has an anti-radiation variant, known as the FT-2000 for export. The export designation for air defense version is FD-2000 (with FD stands for Fang Dun, meaning defensive shield), and its developer China National Precision Machinery Import and Export Corporation (CPMIEC) first made it public at the Africa Aerospace and Defence Exhibition held at Cape Town in March 2009. The HQ-9 had also being submitted by CPMIEC for Turkey's T-LORAMIDS program to acquire 12 long range air defense systems.
